Generate Load Settings for all BinaryView Open Operations and Enable PIC Rebase Setting By Default

[bpotchik]

We should modify the open procedure in the UI to generate load options (via GetLoadSettingsForData) for all open operations. This means that opening a file without using the 'Open with Options' dialog will still generate a load schema.

Along with this change we should enable the files.pic.autoRebase setting by default. This will generate better analysis by default, and result in consistent behavior whether or not a file is opened via 'Open with Options'.

Headless, via the load API already defaults to generating load options by default, whether or not they are provided as an argument.
